bumphing 

instead of masturbating, one furiously rubs his dick on a mattress. usually he starts slow and quickens the pace after about 10 mins. Bumphing usually leads to long hard orgasms. The aftermath is usually a wet bed and a underside dickburn. Usually it leaves the person concentrated and satisfied.

Mom: What happened to your bed? Its been wet since this morning!
Son: Sorry mom, I was bumphing before I went to school, it helps my concentration.

Bumping the lamp 

To go above and beyond expectations when completing a given task/project.
A genericized phrase originally used within the animation industry and the film industry as a whole. Based on a scene from the 1988 mixed live-action/animated film 'Who Framed Roger Rabbit' in which the main live-action character, Eddie Valiant, bumps into a ceiling lamp whilst handcuffed to the main animated character, Roger Rabbit, causing the lamp to continually swing back and forth throughout the remainder of the scene.
The term refers to how the animators went on to meticulously hand-draw unique shadows for the animated character for every frame of the scene.
The phrase went on to become a company mythos for the Walt Disney Company, then as a guiding principle within the greater film industry, and now sees use generally.

We follow the mythos of 'bumping the lamp' with the service at our veterinary practice.

Boffin 

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.

According to the boffins downstairs, the murderer used a serrated blade.
